← The X-Files The X-Files: Mythology episodes 70 television episodes plus Fight the Future, in viewing order. Follow the conspiracy across eleven seasons, retaining one standalone extra from the earlier selection. Watch the film after season five; it is included in the 71-entry count.
For viewers who want the continuing mythology. Most standalone cases and their smaller character moments are outside this route.
Open episode checklist ↓ Mythology episodes · 71 Mythology and the classics · 94 Path details & story map Before you choose a route The mythology reader contains 70 TV episodes and the 1998 film Fight the Future. The film belongs between season five and season six, and is included in the displayed 71 entries and runtime. The broader path adds 23 TV episodes; neither is the whole show.
S05E06 and S05E07 are a two-part story: keep both. S05E05 remains as an explicitly marked standalone extra from the earlier selection, rather than being described as mythology.
The second film, I Want to Believe (2008), belongs between seasons nine and ten if you want that additional standalone case. It is not in this catalogue, either checklist or their runtime totals.
